Closes #58

Based on #72 for convenience.

TODO:

  • Fix up COWD implementation (need to regenerate test data)
  • Add more test data (e.g. snapshots), perhaps generated on ESXi
  • Add benchmarks and compare to previous implementation

This implementation aims to be a little simpler than the previous one, but we should be wary for performance degradation.
